The Audiolab DC Block Audio Grade Main Filter & DC Blocker is a premium metal-encased device designed to remove DC from AC power supplies, reduce transformer hum, and suppress RF interference, resulting in noticeably improved audio component performance and cleaner sound reproduction.

## Description

DC blocks are designed to improve the quality of AC power to power audio and AV systems. From power to amplifier, speaker, the main power supply has a fundamental impact on the audio signal when passing through the system. Common residential main power sources are susceptible to interference caused by various issues, and the AC waveform will be distorted before reaching each component. This creates noise in the audio signal and decreases the sound quality. The more electrical appliances used in your home have increased, the situation continues to deteriorate.
